What I claim as new, and desire to secure by Letters Patent, is-

1. In a clock-regulator, the combination of a revolving tubular a: bor gearing with the clockinovemeut, a compound revolving and sliding arbor carrying the minutehand and extending through the tubular arbor, friction-disks fixed to the arbors,respectively, a balance- Weight fixed to the arbor of the minute-hand, a pusher adapted to be actuated by fluid-pressure, and a means for connecting the pusher with the arbor of the minute-hand, the whole adapted to operate substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of twosubscrib ing witnesses.
